[PATCH 1/2] gpio: of: Check propname before applying "cs-gpios" quirks

[Andrey Smirnov <andrew.smirnov@xxxxxxxxx>]

SPI GPIO device has more than just "cs-gpio" property in its node and
would request those GPIOs as a part of its initialization. To avoid
applying CS-specific quirk to all of them add a check to make sure
that propname is "cs-gpios".
